DOS Attack alarm

[oleodegard]

Hi,

We keep getting these messages from time to time - at apparently random intervals and switches - our NOC then promptly informs us of the alarm - but since we have neither a way to stop what's going on - nor know what is causing it. I wonder - is there a way to disable this? Documentation seems to not tell me how to configure - just that the feature exists.

Ports that generate the alarm are unknown - but we use these switches to deliver triple play services - there is a CPE attached that is under our control.
One VLAN per customer- central 6850's is adding QinQ towards the SR-7 where the MSAP's are generated.

Alarm as seen in CA Spectrum:

The sending agent has received a DoS attack.

Question 1: What is going on? - Any tips as how to identify that?
Question 2: How do I disable just these traps, and not other traps that the switches will send.

so you don't know what a DOS (Denial of Service) is??? O.o
I wouldn't be a happy customer if my network receive such attacks and then my provider/admin just decides to disable alarms and not fix the security hole I am having on my network....
